Best played as ...

[Gary McClellan]

There are a few reasons where a given scenario might be listed as being for one side or the other.

One thing is that some scenarios are not always especially interesting from both sides. Even if you juggle Victory Conditions as much as you like, sometimes a scenario is so one sided that it just doesn't hold interest. Generally, if I've listed a scenario in this way, that's the reason.

As others have started, the AI is a limit as well. I'll admit, the AI in all of the games can be frustrating, and sometimes, the scenario designer just has to say "it will go better for you if you play one side or the other." (Usually the attacker).
